On the spiral structure of the Milky Way Galaxy [PDF]
Astronomy Reports, 2010 We consider the possible pattern of the overall spiral structure of the Galaxy, using data on the distribution of neutral (atomic), molecular, and ionized hydrogen, on the base of the hypothesis of the spiral structure being symmetric, i.e. the assumption that spiral arms are translated into each other for a rotation around the galactic center by 180

A model of habitability within the Milky Way galaxy. [PDF]
Astrobiology, 2010 We present a model of the galactic habitable zone (GHZ), described in terms of the spatial and temporal dimensions of the Galaxy that may favor the development of complex life. The Milky Way galaxy was modeled using a computational approach by populating

The mass of the Milky Way galaxy [PDF]
The Astrophysical Journal, 1995 We use the Jaffe model as a global mass distribution for the Galaxy and determine the circular velocity $v_c$ and the Jaffe radius $r_j$ using the satellites of the Galaxy, estimates of the local escape velocity of stars, the constraints imposed by the ...

Wormhole in the Milky Way galaxy with global monopole charge
European Physical Journal C: Particles and Fields, 2022 Wormholes are tunnels or short-cuts in space-time, and their existence is very important for human civilization to express the vastness of space and time. So, it is necessary to analyze our own Milky Way galaxy if it can harbour any wormhole.

The Milky Way and other spiral galaxies [PDF]
EPJ Web of Conferences, 2012 Cosmologists have often considered the Milky Way as a typical spiral galaxy, and its properties have considerably influenced the current scheme of galaxy formation.

Black holes in the milky way galaxy. [PDF]
Proc Natl Acad Sci U S A, 1999 Extremely strong observational evidence has recently been found for the presence of black holes orbiting a few relatively normal stars in our Milky Way Galaxy and also at the centers of some galaxies. The former generally have masses of 4–16 times the mass of the sun, whereas the latter are “supermassive black holes” with millions to billions of ...

Microlensing Maps for the Milky Way Galaxy [PDF]
The Astrophysical Journal, 2002 At any instant, there are ~1000 microlensing events to sources brighter than 20 mag in the Milky Way. Large-scale maps of the microlensing optical depth and the mean timescale are constructed for a number of models of the Galactic bar and disk ...

CHEMODYNAMICAL SIMULATIONS OF THE MILKY WAY GALAXY [PDF]
Proceedings of the International Astronomical Union, 2008 We present chemodynamical simulations of a Milky-Way-type galaxy using a self-consistent hydrodynamical code that includes supernova feedback and chemical enrichment, and predict the spatial distribution of elements from oxygen to zinc.

The mass of the Milky Way Galaxy [PDF]
Monthly Notices of the Royal Astronomical Society, 1992 We present a method for determining the Galactic mass and mass distribution based on maximum likelihood parameter estimation. We show that the number density of the Galaxy's outer satellites can be modelled by a power-law function. Assuming that the total distribution of matter (visible and dark) can be modelled in a similar way, we construct a self ...

The Astrophysical Journal, 2023 In the Λ-Cold Dark Matter model of the universe, galaxies form in part through accreting satellite systems. Previous works have built an understanding of the signatures of these processes contained within galactic stellar halos.
